Abstract: A hair iron according to one example embodiment includes a first arm and a second arm movable relative to each other between an open position and a closed position. A contact surface is positioned on an exterior of the first arm for contacting hair during use. The hair iron includes a heater having a ceramic substrate and an electrical resistor material thick film printed on a surface of the ceramic substrate. The heater generates heat by applying an electric current to the electrical resistor material. The heater is positioned to supply heat to the contact surface.

Abstract: A magnetic field z-gradient coil is manufactured by inserting elements (38) into openings (36) on an outside of an insulating carrier (32), wrapping an electrical conductor turn (34) around the outside of the insulating carrier with one side of the wrapped electrical conductor alongside elements inserted into openings on the outside of the insulating carrier, removing the elements alongside the one side of the wrapped electrical conductor from the openings, and repeating to wrap conductor turns of a z-gradient coil (20) around the electrically insulating carrier. A transverse magnetic field gradient coil is manufactured by laying electrical conductor (44) onto a mold (50) with a keying feature (46, 46a) extending along the conductor engaging a mating keying feature (52, 52a) of the mold that defines a winding pattern (56), attaching an insulating back plate (58) to the resulting coil section opposite from the mold, and removing the mold.
